Aeterno and the Aeterno AI Model Asset Platform

Where we come from

Aeterno began in 2020 as an energy standards consultancy. We built and validated detailed building energy models for UK and European standards bodies, contributing to the next generation of domestic building standards.

That work gave us two things: a deep understanding of how homes and systems really behave, and a library of thousands of modelled domestic buildings to learn from. Aeterno AI is the product of those lessons—a Model Asset Platform designed from day one for real-world performance and governance.

What we've already proven

The Aeterno AI platform is in active use and has been used to generate and manage thousands of Model Assets for domestic buildings over multiple years.

We work with leading OEMs in home energy to power production workflows—from standards-aligned design tools through to daily quotation and optimisation systems. Some of this work is under NDA; we provide detailed evidence packs and references in confidence as part of due diligence.

What we focus on today

Today, Aeterno AI focuses on two verticals where lifecycle value and governance matter most:

• Home energy OEMs — Per-home Model Assets used for design and sizing, commissioning, warranty triage, performance tuning and flexibility programmes.
• Commercial buildings and estates (EMCs) — Per-site Model Assets used for PPM, anomaly handling, service dispatch, compliance and optimisation.

The same Model Asset pattern and Assist → Auto governance can be applied in other asset-heavy domains, including manufacturing, automotive, aerospace, robotics and finance.

How we work with customers

We typically start with a contained proof of value on live data before expanding coverage and automation.

• Scope — 1–2k homes, or a representative set of buildings across an estate.
• Mode — Assist-only, complementing existing tools and workflows—no rip-and-replace.
• Governance — Jointly agreed KPIs, clear approval gates, and exportable evidence logs.

Once value is proven, we expand coverage, increase automation and extend along the asset lifecycle together.
